, My invention relates to ironing machines and it has specialrelationlto ironing machines of the domestic type.

' An object of my invention is to provide a device that shall makeconvenient the ironing-of large pieces on small ironing machlnes. s

A further .object of my invention is to provide a device adapted for usein the ironing of large pieces in an ironing machine, for supporting andadvancing that portion of an article to be ironed which extends beyondthe end of the machine, in correspondence. with the advancement ot that.part ofthe article which is being ironed.

Other objects 'of my invention will appear'` as the descriptionproceeds.

Referring to the drawing:

Figure 1 is a .rear elevational view of an ironing machine with myinvention applied thereto.

Fig. 2 is a longitudinal central sectional view of the roll shown inFig. 1.

D Fig. 3 is adetail sectional view of the roll and cooperating parts,portions being brokenl away, and

Fig. 4 is a' view of the right end of the roll, parts being broken awayto facilitate illustration. Y

An ironing machine embodying my invention comprises a roll 1, a shoe 2and standards?) and 4 for supporting the roll and the shoe. Insteadofthe shoe, a heated roll may be used if desired.

The ends of the roll 1 are mounted on a pair of spiders 5 and 6 that aresecured to a longitudinal -shaft The end of the roll at which the spider5 is provided, has no immediate support other -than the spider 5 and theshaft 7. It is of thetype commonly referred to in the art: as open Eachof the spiders 5 and 6 is provided with a plurality of holes 8, eachhole of one spider being connected to a corresponding hole of the otherby an 'elongated tube 9. The tubes-9 may be of' any desired number andare adapted to receive slidable tubes 10 which are secured to a head 11.

limited by stops, 12 thereon which engage detachable stops 13 in thetubes 9. Y

Tubes 14 rigld with a head 15, are slidable in the tubes 10 but limitedin their outward port for articlesI Outward movement of the tubes 10ismovement by stops 16 which engage detachable stops 17 'in the tubes10..

COMPANY, A CORPORATION OF PENN- When small pieces are being ironed, the

tubes 10 and 14 are of the roll'v 1, being completely enclosed thereby,as indicated by dotted lines in Fig. 3. hen comparatively wide piecesare being ironed, the heads are drawn outwardly to the position shownin' full lines in Figs. 1, 2Kand 3. The articles are then passed betweenthe roll 1 and the shoe 2 and those portions of the articles which arenot positioned interiorly subjected immediately to an ironing action bythe shoe 24 are supported and' carried by.

the tubes 1() and 14.

When an article is draped over the tubes 10 and 14, it is given asemi-cylindrical shape conforming substantially to the shape imparted tothat portion of an article which is on the roll. It is not necessary inorder to impart a semi-cylindricalshape that the tubes 10 and 14 shouldbe of the specific number illustrated. It is apparent, therefore, thatwrinklingfof that art of the article which is beyond the en of the rollis avoided. l

In addition to preventing wrinkling, the tubes facilitate the feeding oflarge pieces by reason of the fact that; n`o special care portions ofthe pieces end of the roll, since need be taken of those which arebeyond the they are carried by thetubes and advanced in correspondencewith thev portions that are on the roll.

If desired, the tubes 14 need not be moved outwardly with respect to thetubes 10 but the tubes^10 only may be utilized as a supbeing ironed.'Again, if desired, the tubes 10 and 14 and heads 11 and 15 may bedispensed with altogether, as the detachability of the stops 13 and 17permits their removal.

In the case of an 18 roll, the tubes 10,'in their extended positions, mabe made to v project 12. beyond the end o the roll 1, 4

tubes 10 during the rotation of the roll. 4In a machine of thesedimensions, the tubes 14 may have a corresponding and` proportionallength with respect to the tubes 10. In they case of an ironing machinehaving a 30 roll, the tubes 10 only are .1 2 ry, as suplsively modifiedand varied without departing fromthe spirit of the invention. Forinstance, Instead of the extensible tubes, any support maybe used thatis adapted to rotate with and telescope in, the roll. Again, a'

support may be used whichl does not telescope with the roll but isattached ythereto and removable therefrom. A substantial range ofequivalents is contemplated within the scope of the4 appended claims.

I claim as my invention:

1. In an ironing machine, in an ironinv roller and a Work supportcarried by the rol said Work support being disposed intelescopicrelation with the roll. i

2. The combination of a heated ironing member; a roll having an openend, and extensible means projecting from the open end of said roll, andmovable therewith for supporting and advancing an article to be iro'ned,said means. being operative to supcombination, i

portisaid article in. substantially theV same shape. as that portionofthe article between said member and said roll.

3. The combination of a heated ironing` member, a roll, and extensiblemeans ron said -roll for supporting and advancing an article to beironed.

4. The combination with a heated ironing member and a roll cooperativeto perform ironing operations, of means movable to be completelyenclosed. by saidl roll and extensible to pro]'ect beyond said ro'll forsupporting that portion of said article which is not immediatelysubjected to ironing action.

5. In au ironing machine, the combination with the heated ironing'member and a roll cooperative lto perform ironing operations` of amember extensible with respect to said roll Iand an additional mem'berextensible with respect to the first mentioned extensible member, thetwo .last mentioned members being adapted to support that portion ofjected to ironing action.
